` BALL-coca Application tiled July 22, 1907. Serial No. 384,831.

To ai] 'whom it may concern:

Be it known that I, Gnouot: E. Yan Deusnx, a citizen of the United States, rcsidirwr at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in BallCoci\:s, o which the-followinof is a full, clear, and exact. description, reierence being had to the accompanying drawings.

This invention relates 4o ball cocks or float valves of the type which are employed in liushing tanks for the purpose of automatically cutting-ofi the supply of liquid to such tanks when thepliquid has reached a predetermined level therein.

lit has for its objects tol provide a cock of this type with a double or reversible plug or avalve body having at. both endsmeans for fomning an eective cut-oli with its seat; also to provide for cocks of this type an eliicient union which is located inside of the tank, whereby any leakage at said union -will be confined entirely within the tank;

also to rovide a union which while located within t e tank, can be disconnected without the necessity of the employment of tools which, owing to the inconvenient location of the flushing tanks and the limited space provided therein, are often extremely dilii cult of a plication; to provide connections between t e ball or tioat and the plug which Y will permit the employment. of a small ball 'and a short connecting rod and which, when the ball rises to its upper limit of movement and thereby shortens the etective length of the lever rod by which the ball is supported, will give a greatly increased leverage in the short arm of the lever which acts upon the valve plug and enable it, ai the extreme lift of the float, to exert a locking action on said plug 'to provide the valve with means which shall permit of the free flow of liquid there throu also to provide a water-packed joint or the valve plu A further object o the invention is to provide a construction of valve or cock which may be convenientlyassembled, which will be free from fluttering or other objectionable noise and which will permit the rod or lever by which the ball is carried to be permanently connected to its pivotal support or fulcrurn.

Generally speaking, the invention may be defined as consistin of the combinations of Elements embodied 1n the claims hereto annexed and illustrated in the drawings forming part hereof, wherein Figure 1 represents a side elevation of a hall cock and connections constructed* in accordance with my invention, a portion of the tank being shown in section. Fig. .2 represents an enlarged sectional view of the cock or valve and the connections between the same and the bottom of the tank. Fig. 3 represents a sectional view on the correspondinly-numheredline of Fig. and Fig. 4 represents a perspective detail of the plug or valve body.

Describing the; parts by reference characters, 1 represents a tank of any approved construction, the same being shown as a wooden tank provided with a sheet-metal lining 2.

3 denotes the supply pipe by means of which liquid is supplied to the interior of the tank. The upper end of supply pipe 3 is connected to the lower end of an inlet conuection Sleeve or union 4 by means of a gland nut 5 having a shoulder ada ted to engage a flange 7 on the upper end o pipe 3 and provided with an internal thread by means of which it may be adjusted along the threaded exterior of connection si. A washer 8 is interposed between the upper end of pipe 3 and connection 4. This connectiou 1s inserted through the aperture 9 in the bottom of the tank and is provided with a liange 10 above and of greater diameter than said aperture, said flange resting upon a Washer 11. By means of a clamp nut 12, connection 4 may be drawn downwardly to provde a tight lit between flange 10 and washer 11 and prevent leakage through the aperture 9. The u per end of connection 4 is also provided willi a flange 13 provided on its exterior with a screw thread and having a central bore 14 therethrough of smaller diameter than the main bore 15 of said conne@ g i l l, tion.

l To the upper end of connection 4 my valve i is applied, said valve comprising a sleeve 0r l casing 16 which is detachably secured to the upper end of said connection. Thls sleeve or l casing comprises a tubular body having at the lower end thereof a flange 17 by means of which the lower end of said sleeve crcasing is clamped upon the washer 18, said washer resting on top of the u perlend of connection 4 and being provide with a central bore 19 adapted to receive allonge or 110 Patented Feb'. 8, 1910.V

short tubular extension 13 of flange 13 l whereby the washer is centered and the uccess of water beneath the saune is prevented, l thereby preventing fluttering of the washer. i To further prevent this fluttering action, the bottom of tie sleeve or casing l!) is flanged inwardly at 16H, reducing the freeuu'eu of. the washer between the bottoni of the sleeve or easing and the c 'nter thereof. f

To secure theI sleeve or casing on top of i connection 4, I employ a gland nut or union g 20'comprising a depending inicriorly thread` ed sleeve adapted to be. screwed upon the exi ternal thread of flange 12 and prorided with i an inwardlyprojecting shoulder or flange l 21 adapted to engage flange 1T and rrn-g ly clamp the sleeve or using 16 against the. f' Washer 18. F or the purpose of operating the i gland nut or union 2O wit-hout the necessity A of the employment of u wrench or other tool, said nut is provided with a pair of operating arms 22, preferably cast therewith und projecting in opposite directions therefrom. At i ashort distance above flange 1i', casing or Q sleeve 16 is provided with anp-air of oppol sitely located ports 23, forming a free und l unobstructed passageway for the water supplied to the tank through connection 15@ Above said ports, easing 1o' is provided with i an inwardly projecting annular flange El. and at the top with a flange or shoulder 25, saidiianges being of the suine internal diameter, a chamber 26 being provided between said flanges. l'v'ithin the sleeve Orensing 16 there is litted a vulve body or plug I 2i". This plug is of cylindrical shape and g the diameter thereof is substantially equal g to the internal diameter of llnnges 24 and 25, l which, With the chamber 2G, forni n wuierpacked joint for said plug. This plus is.. symmetrical throughout its extent und is provided at each end with a circular recess 2S surrounded by a narrow 1-.ange or ring 29 which is formed by. the project-ing of the plug. This construction of the valve plug enables it to be reversedwhen the end which has been in engagement with the 'valve sont becomes worn and se gives double the life of the ordinary plug. This ring is of greater diameter than the aperture 19 in washer 1S and forms a ring seat with saidwasher which eifectively shuts ori' communication between the connection 4 and the interior of the tlnk when the plug is seated.

'The sleeve or casing lf3-is provided with a pair of inclined arms or lugs 30 projecting upwardly from the upper central portion thereof. The upper ends or' these lugs are provided willi apertures for the reception of the pivot 31 of the ball rod. Owing to the inclination of lugs 30, these apertures :1re :it one side of the axis of the casing 16, as will appear more particulfulY from :in inspcctiou of Fig. 2. 32 denotes the ball or tion! by menus of which the vulve is closed determined level.

large ports Q3, located adjacent to tle aperture 19, the movement of the plug within the casing or sleeve 16 being facilitated b v the water-packed joint formed by and between flanges 24 and 2.3. Owing to the shape of the connection 34, the location of the pivo'tal connection between the same and lugs 30 and the location of screw 37, as the float rises the lower end of the screw approaches a a line drawn through the pivot of the lever, the cavity in the top of the plug facilitating this action. As the ball approaches the upper limit of its movement, a short lever arm is rovided between the pivot of the lever an the lower end of 3T, the effective length of this lever decreasing faster than the decrease in the effectiveV length of the lever interposed between the ball 32 and the pivot. In this manner an increasing# leverage is exerted by the ball and its rod upon the top of the valve plug as the ball rises and, at the upper limit of movement of the ball a locking action is exerted upon the top of the plug, as will.' appear from Fior. 1. I

ily construction permits of great convenience in asembling the valve. the fact that the plug maybe inserted from the bottom of the `leere or casing lG, the ball lever may ermanently connected 'to the lugs 30, as by t e rivet 36. The union sleeve or gland nut 2O may be slipped over the upper end of rod 33 and over casing 16 before the ball 32 is threaded or otherwise secured to the end f'said rod.

The particular ((:l'nstruction of the plug not only forms a very etlicicnt joint between the bottom thereof and the top of the washer 18. but, owing to the reversibility of the plug, the life of the valve is doubled.
